As President Joe Biden prepares a final decision on the huge Willow oil project in Alaska, his administration says he will prevent or limit oil drilling in 16 million acres in Alaska and the Arctic Ocean. Plans announced Sunday night will bar drilling in nearly 3 million acres of the Beaufort Sea closing it off from oil exploration and limit drilling in more than 13 million acres in a vast swath of land known as the National Petroleum Reserve - Alaska. The moves come as regulators prepare to announce a final decision on the $8 billion Willow project, a controversial oil drilling plan pushed by ConocoPhillips in the petroleum reserve.
